never mind figured it out... so how now how can I get ride off that line where the chamfer starts??

so I got up to the offset and putting a guide down to where I want the chamfer but I don't understand how to now drop the edges

I want to make a chamfer edge on the inside edge of a hollow box. see picture below. I am trying not to have to make each individual sides, as this is just a conceptual drawing for a client.

perfect thanks guys... but why did it do this in the first place? its not done this before?? is there some setting I did by mistake that I can change?

so some how when I try and push a rectangle through instead of it just ending and pushing through at the end of the parallel face it continues... what setting did I do to do this? I just want it to push through like a window...

see picture...

never mind got it figured out... thanks again

ok so I spoke to soon... I can't find intersect faces, so when I select all the object and click on intersect and then use the eraser it deletes all the objects

thanks guys for the quick response... I didn't think it was that complicated but just didn't know what to do...

I am trying to make a miter joint on one edge of a rectangle on another edge I want to make a chamfer but can't seem to find a way to do this. see photo's attached
